Sunan Abi Dawud, Hadith 4045 ⓘ
Narrated Anas: The Messenger of Allah gave license to 'Abd al-Rahman b. 'Awf and al-Zubair b. al-'Awwam to wear silk shirts during a journey because of an itch which they had.
حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا عِيسَى، - يَعْنِي ابْنَ يُونُسَ - عَنْ سَعِيدِ بْنِ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ رَخَّصَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَلِلزُّبَيْرِ بْنِ الْعَوَّامِ فِي قُمُصِ الْحَرِيرِ فِي السَّفَرِ مِنْ حِكَّةٍ كَانَتْ بِهِمَا .
